Let us use carbon in this example. Carbon is 12.01 grams per mole.
Let us say we have 2.36 X 10^22 atoms of carbon
2.36 X 10^22 atoms carbon (1mole Carbon/6.022 X 10^23)(12.01 grams Carbon/1mol Carbon )
= 0.47 grams Carbon.
6.022 X 10^23 is Avogadro's number and is a constant that is a mole of anything. Just as a dozen eggs is always 12 eggs.

∙ 11y ago1 mole = 6.022 x 1023 atoms = molar mass in g/mole
?atoms x 1 mole/6.022 x 1023 atoms x molar mass = mass in grams
For example: What is the mass of 2.00 x 1024 atoms of carbon?
Answer: 1 mole C = 6.022 x 1023 atoms C = 12.0107g/mole C
2.00 x 1024 atoms C x 1 mole C/6.022 x 1023 atoms C x 12.0107g/mole C = 39.9g C

2. Divide the mass of the element by its atomic mass.
3. Multiply the result by Avogadro's Number.

What relationships are needed to convert 1.5 grams of carbon to the number of carbon atoms?
molar mass and Avogadro's number
How do you convert chlorine atoms to moles of chlorine atoms?
To convert the number of chloride atoms to mols of chlorine atoms, simply multiply by Avogadro's number. This number is 6.022E23. Note that chlorine typically exists as a diatomic molecule, consisting of two chlorine atoms.
How do you convert atoms to grams with Avogadro's number?
divide the number of atoms by avogadros number (6.022*10^23), the resulting number is the number of moles you have. Multiply the number of moles of atoms by the molar mass (found on any periodic table) and the answer is how many grams of the substance you have.
Why is it necessary to convert given units of substances to moles when solving a stoichiometry problem?
We convert units to moles because in reactions atoms of different elements combine in simple whole-number ratios. The whole numbers are related to the number of atoms, not their weights.
To convert a given number of moles into the number or atoms you would multiply by which factors?
You would multiply the number of mols by Avogadro's number which is 6.0221415 x 1023

How to convert grams to atoms?
To convert grams into atoms, you have to convert them into moles first. Get the molar mass and multiply it by the number of moles to get the atoms.
How do you convert chlorine atoms to moles of chlorine atoms?
To convert the number of chloride atoms to mols of chlorine atoms, simply multiply by Avogadro's number. This number is 6.022E23. Note that chlorine typically exists as a diatomic molecule, consisting of two chlorine atoms.

How many hydrogen atoms would be needed in an addition reaction to convert one molecule of 2-pentene to one molecule pentane?
The molecular formula of 2-pentene is C5H10 and the molecular formula of pentane is C5H12. Therefore, (12 - 10) or 2 hydrogen atoms per molecule will be needed to convert pentene to pentane.
To convert a given number of moles into the number or atoms you would multiply by which factors?
You would multiply the number of mols by Avogadro's number which is 6.0221415 x 1023
Which has the greatest number of atoms- 3.5 grams of helium or 3.5 grams of lithium?
Helium because it has fewer atoms, so there are more atoms needed to have 3.5 grams of it.

Bonds are needed in order for atoms to combine
How do you convert grams to atoms with the avogadro's number?
(grams) x (6.02 x 10^23) / (mass number of specific element in grams)
How many Cu atoms are their in3.7x103 millimole?
3.7x10^3 millimoles is 3.7 moles. To convert moles to atoms, multiply by avagadro's number. 3.7 x 6.022x10^23 is 2.22814x10^24 atoms.
How can you convert the number of atoms of these isotopes 35Cl and 37Cl to percentage?
Chlorine-35 is 76 % and chlorine-37 is 24 %.
